Oakridge Secures Grant for Solar Project at the Willamette Activity Center

The Willamette Activity Center (WAC) Fundraising Group is excited to announce another recent grant award! The City of Oakridge was awarded $332,500 through the Oregon Department of Energy (ODOE)'s Community Renewable Energy Program grants (C-REP). This grant will support rooftop solar panel installation with battery backup at the WAC. This project will allow the WAC to produce electricity, reducing day-to-day costs to operate the building and guaranteeing power when Oakridge power is cut off from Eugene. Electricity production and storage enhances the WAC's role as a Lane County "Resiliency Hub", and is one of six located throughout Lane County.

The WAC Solar Project is one of 34 initiatives selected for funding by the ODOE to provide nearly $18 million across the state. The competitive selection process evaluated projects based on feasibility, equity, cost savings, and economic development potential.

The C-REP grant and nine others have been awarded due to the WAC Fundraising group’s coordination and efforts, bringing the total to $6.3 M!

Field Tour Gives Neighbors a Chance to Weigh in on the Future of Wildfire Resilience

The annual wildfires that threaten residents near Oakridge Oregon bring more than just smoke and a charred landscape. They also bring evacuation orders, anxiety, and with that, the important question: What is being done to protect our communities? While the wildfire crisis is here to stay, there is room for hope in proactive management. In September of 2024, members of the public got to see what the local Forest Service district has done and is planning to do, on Dead Mountain east of Oakridge. 


Along with Southern Willamette Forest Collaborative members and staff, neighbors who live near the project area got to have an open dialogue with Forest Service staff about the area they see as their backyard. Dead Mountain has a long history of significant fires, including stand-replacing events in 1910 and 1967. More recently, in 2023, the Salmon Fire was fortunately contained at 100 acres. However, nearby fires such as Kwis (2021) and Cedar Creek (2022) have burned large portions of the Salmon Creek and Black Creek watersheds. As a consequence, the communities of Oakridge, Dunning Road, and High Prairie have faced evacuation orders every summer for the past four years.

Currently, Dead Mountain faces both short-term and long-term wildfire risks. In the near future, the area is at higher risk of catastrophic wildfires due to overstocked stands and dead fuels from blowdown events. Looking ahead, the risk will increase as trees killed by crown fire in the nearby Cedar Creek fire area eventually fall, adding more fuel to the landscape. These compounding factors underscore the importance of proactive forest management and community preparedness in this fire-prone area. 

This is where the Forest Service East Oakridge Strategy comes into play. The strategy will unfold in three phases, each involving an Environmental Assessment (EA). These EAs are incorporating an innovative approach called Potential Operational Delineations (PODs). PODs essentially divide the landscape into manageable compartments based on natural or human-made features that can be useful for both wildfire response and fuels management. The first POD includes Dead Mountain and will focus on landscape treatments such as thinning and creating shaded fuel breaks. These efforts aim to balance forest resiliency with fire mitigation goals. As the environmental analysis progresses, the Southern Willamette Forest Collaborative (SWFC) is committed to keeping the public informed and engaged, ensuring opportunities for community/ public participation throughout the process.

Disaster Preparedness Trainer Ana-Marie Jones Brings Positive Message to Oakridge

Nationally-Recognized Trainer Ana-Marie Jones kept the participants actively engaged for hours.

When most of us think about disaster preparation, we think about mass food storage and survival gear. But when it comes to your average disaster, knowing your neighbors and having a ‘MacGyver’ mindset is just as important. That was one of the messages that disaster preparedness trainer Ana-Marie Jones (aka ‘Ms. Duct Tape’) gave to a workshop in Oakridge last June. 30 people attended the workshop including community leaders, agency partners, nonprofit staff, and local public. Most of them were part of the Oakridge-Westfir Community Disaster Readiness Group (CDRG). The CDRG has been meeting since May 2023 to build skills that can help first responders with disaster response, and this training was a big first step. 

Ana-Marie's message questioned some ideas about being ready for disasters. Typically, when organizations talk about getting ready for disasters, they use fear to get people to listen. But Ana-Marie shared strong proof that we should try a different, more positive way. When we share messages that make people feel capable and connect with their neighbors, we make better plans that last a long time. When we're only scared, we might do something quickly, but then forget why it matters once the fear goes away. Being hopeful and positive isn't just a good idea; it's really important for making our future safer when a disaster happens.

Ana-Marie reintroduced disaster response concepts in a way that is easy to remember. One of the most important parts of coordinated emergency response is the Incident Command System (ICS). However, this system can seem confusing, boring, and not very useful to the average person. This training helped people understand how ICS can be used as effectively in setting up a neighborhood potluck as it can be after an earthquake. If volunteers know their roles and responsibilities, they can be useful without getting in the way of first responders.

The Readiness Group wants the public to know that disaster readiness training isn’t scary, and is something that anybody can do! Whatever skills you have, we need them. Everybody, no matter their level of expertise, has something they can contribute. Oakridge and Westfir have seen these ideas come out during disasters such as the 2019 winter storm. Planning ahead for the next disaster simply takes a little planning, a few meetings, and knowing your neighbor. The first step? Throw a party or just get to know each other.

The Community Disaster Readiness Group hopes to invite back Ana-Marie for a training next month. If you are interested in joining the CDRG, WE NEED YOU! We are currently recruiting neighborhood leaders and figuring out how to best use our members’ skills. Please Fill out This Form to sign up and to help first responders fill gaps when disaster strikes.

Sustainable Energy in Rural Oregon: Solar, Micro-hydro, and Biomass

The Southern Willamette Forest Collaborative went on a road trip in September to attend the 2021 Sustainable Northwest "Making Energy Work" Symposium. Attending from the SWFC were Sarah (SWFC Coordinator), Laurie (founding Board Member) and Dustin (Outreach Coordinator and RARE AmeriCorps member), and joining from the City of Oakridge was Grace (Economic Development Coordinator). The event lasted three days and featured a large selection of experts on sustainability solutions for rural Oregon. The symposium also showcased an impressive range of innovative and practical projects.

Wallowa Lake as seen from the Chief Joseph National Historic Landmark

Wallowa County is a true Oregon gem. It is the home of Wallowa Lake, Hell’s Canyon, and the “Oregon Alps”. Though tourists find their way here in big numbers, the county is rural and farm based. Wallowa is not a place one might link with cutting-edge climate change solutions. Yet, for hundreds of years, locals have relied on naturally-powered machines like watermills. In modern times, new ways to power communities have found their way to Wallowa County. These advancements do more than reduce greenhouse gasses. They also help to create jobs, slow wildfires, preserve habitat, and lower the cost of energy. During the conference we saw clearly that the county has a winning formula for clean energy. This formula is what Nils Christophersen of Wallowa Resources calls a “Stewardship Economy”, based on delivering “triple-bottom line” (community, environment, jobs) solutions. 

You get the strong sense that Wallowa Resources (WR) is a key partner in many of the innovative projects. For WR, balancing habitat, economic growth, and community building is a way to help this rural area survive and thrive. Using the stewardship economy model, WR has become a well-known community building organization. There's a lot of talk about potential in sustainable energy. The projects we saw showed us how ideas become reality.



Community Solar meets Affordable Housing

Solar-powered affordable housing in Enterprise, OR.

Solar-powered affordable housing in Enterprise, OR.

Ryan Sheehy of Fleet Development was an engaging tour guide around two inspiring solar projects. The first stop was the site of the soon-to-be constructed Community Solar installation. At first, it looked like an empty hillside in a former asphalt plant. Ryan informed us that, in fact, he considered the work 90% done. The Community Solar program, set in place by Oregon SB 1547 in 2016, was the model for the solar installation. The law allows for individuals to cost-share power from a central solar plant. This solves problems for shaded properties or renters who don’t own their roofs. Government rules require a long approval process, which presents a host of challenges. Connecting to the grid, finding contractors, and gaining community support took up lots of time and energy for Ryan and his partners.

Yet here we stood at a field where in a couple of months, a solar power plant would exist. It will generate enough energy for up to 100 households. 10% of this energy will go to low-income households. It was clear that affordable housing is at the forefront of Fleet Development’s plans. Another project that Ryan has helped  to create is a rooftop solar low-income housing block. Once again, the partners involved had to overcome difficulties of the utility system to come up with creative solutions. Now Park Street Apartments is a sustainable and affordable place to live. Enterprise also boasts rooftop solar panels on its hospital, clinic, a local church, and a wastewater treatment plant which is entirely solar powered. The solar arrays in Wallowa are impressive, but the solutions didn’t stop there. 


Micro-Hydro: Harnessing Water Pressure In Unexpected Places

Housing for the micro-hydro generator at Wallowa Lake State Park

Housing for the micro-hydro generator at Wallowa Lake State Park

The next tour took us to a campground in the stunning Wallowa Lake State Park. Nestled up the slope from the RV campground is a small log cabin. This cabin might house the future of rural hydropower: a “Micro-hydro” generator. Presenters from the Energy Trust of Oregon and Wallowa Resources explained that this generator utilized an existing underground spring. The stream was harnessed to power a Pelton turbine. The project only needed some pipe retrofitting to be compatible with the generator. This method leaves above ground stream ecosystems untouched. The project will power 85% of the water and sewage pump for residents who live near the lake. 

As discussed by a panel the next day, micro-hydro could be implemented in many ways. They plan on installing similar generators during field irrigation upgrades. These generators double as replacements for pressure regulators. The project team had created maps of the entire county which look at water flow, slopes, and access to legal water rights. There are many potential sites  that could tap into this technology. While micro-hydro isn’t going to replace conventional dams any time soon, the potential is promising. 

Heartwood Biomass

 Finally, we got to see a front row seat to a type of project that holds opportunity for many PNW communities: biomass utilization. "Biomass" can mean many things to many people. Essentially, it is any process that converts organic biological material to another, usable form. For Heartwood Biomass in Wallowa, it means improving forest health and reducing the chance of severe wildfires. Heartwood turns the woody refuse created in the process into an array of products. While they transfer some logs to traditional mills, most become poles for hops growers, posts, firewood, veneer, and more. 

 Another Biomass product is biochar, which Heartwood has created before. Their facilities still need an upgrade before they can produce it consistently. The promise of new markets like biochar might have to wait for now. But other traditional wood products markets are going strong. For instance, Heartwood produces a lot of firewood, which they kiln dry with other by-products from the process. Yet, they choose to send it all out-of-market, allowing woodcutters to survive. They employ around 25 workers, and are currently hosting another company’s veneer production on their facility.  Like others in Wallowa, Heartwood has made the triple bottom line a reality. 


Takeaways

We could imagine many ways to integrate these projects into a south Willamette watershed sustainable energy system. We have waterways, sun, and, of course, lots of biological material that could be used.  Generating power from micro-hydro in existing springs and wells in Oakridge could certainly be a reality. Imagine powering public buildings and affordable housing with a local source of energy. The potential for increased disaster preparedness from these sources is also exciting.  Community building takes time, effort, patience, and leadership. 

Each of these projects needs a champion like Wallowa Resources. None of them came to pass without significant inter-agency coordination and private-public partnerships. They each had many phases including planning, funding, site selection, construction, and management.  These innovative sustainability projects in Wallowa Co. took at least three years in every instance. Factoring in the social connection that needs to be built to make them work, each of these projects can be seen as decades-long.  The Southern Willamette Forest Collaborative is aiming to learn from  what Wallowa Resources has accomplished and support sustainable triple bottom line solutions that are the right fit for the local communities.










SWFC Director Interviewed for Local Podcast

SWFC Director Sarah Altemus-Pope recently sat down with EugCast podcast host Jojo Jensen to talk about wildfires, restoration, and the Rigdon landscape. Sarah shares her perspectives on living with fire, increasing the pace and scale of restoration, and the value of shared learning. She also talks about what may be in the works for Rigdon and future projects, especially as Covid restrictions are lifted. The episode is a great introduction to the work of the Southern Willamette Forest Collaborative for newcomers as well as for folks who could use a refresher on the projects the SWFC is involved with.

EugCast is a volunteer-run conversational podcast based in Eugene, Oregon. Monthly episodes feature guests from Eugene and the surrounding areas discussing a broad range of topics. In addition to Sarah’s episode, collaborative members may be interested in the March 2020 interview with Ian Appow, who coordinates the Wildfire Urban Interface Fuels Reduction Project. Ian has been engaged with Firewise efforts in and around the Oakridge-Westfir community.

Updated December 15, 2020

IMG_5403 (1).JPG

The Willamette National Forest’s Middle Fork Ranger District (MFRD) and the Southern Willamette Forest Collaborative (SWFC) have worked together for four years to develop the Rigdon Landscape Analysis and conduct environmental analysis for an area southeast of Oakridge, Oregon. Fire suppression has dramatically changed the composition of the landscape. The project provides a critical opportunity to move the landscape towards more historical conditions that supported dry mixed conifer forests, diverse indigenous floral understories, Oregon white oak, ponderosa pine, ungulates, monarch butterflies, bull trout, and salmon habitats.

In 2016, the Forest Service interdisciplinary team (IDT) started an in-depth process to assess the ecological systems and identify landscape objectives to create proposed actions. The SWFC Rigdon Collaboration Committee (RCC) - which includes members from the local communities, watershed council, timber industry, recreation and special interest groups, and state and local agencies - formed to engage in the pre-planning process.

National Forest Foundation Community Capacity and Landscape Stewardship Program funding helped the RCC host shared learning opportunities, field trips, and roundtable discussions between the IDT and committee members. The collaborative committee developed landscape-level zones of agreement for the Forest Service to consider in drafting the Rigdon Landscape Analysis and future proposed management actions.

Developing a more thorough understanding of the area’s fire history has led to more informed and complete plans for restoration and monitoring. Funding from the Oregon Department of Forestry and Good Neighbor project revenue enabled SWFC to engage researchers from Oregon State University (OSU) and the University of Oregon (UO). 

IMG_5365.jpg

Bart Johnson, from the UO School of Architecture, is conducting post-implementation monitoring of a 600-acre pilot project to promote Oregon white oak savanna through thinning, reseeding, and subsequent prescribed fire treatments. James Johnston, from the OSU dendrochronology lab, analyzed the fire frequency on the Rigdon Landscape over the past 400+ years, revealing that some areas burned as frequently as every four years while higher elevation stands often went hundreds of years without burning. These findings have helped partners and the agency better understand how to implement restoration activities that lead to a more fire-resilient landscape.

IMG_5367.JPG

The first Rigdon Landscape project, Youngs Rock Rigdon (YRR), is an environmental impact statement scheduled for a record of decision in 2021. Implementing YRR restoration activities with Stewardship and Good Neighbor Authority tools will create a more resilient landscape as climate conditions change, help ensure more restoration within treatment areas over time, and support the local economy. 

The SWFC created a suite of resources to encourage participation in the Rigdon project, including a self-guided field trip of the area using the free Avenza app. You can download the field trip packet, maps, and field trip layer here.

The SWFC also worked with the Forest Service to create a Rigdon StoryMap providing in-depth context about the history and value of the landscape and details about restoration plans, and a video of key stakeholders sharing their perspectives on the project (coming soon). The SWFC highlighted perspectives ranging from timber workers to environmental advocates in a blog series earlier this year.

If you haven't had a chance to make it to a public field trip or just want to investigate the project area at your own pace, you can now take a self-guided field trip using the Avenza app. This tool allows you to learn about the proposed actions related to aquatics, vegetation, wildlife, and human uses for the first project within the larger Rigdon landscape. The app includes geo-located stops, descriptions, and images from the Forest Service and SWFC. Instructions for both Android and iOS are available in the handout below.

Taking a self-guided field trip to the area is a great way to learn about the Youngs Rock Rigdon project scope and plans for restoration. The project's initial public comment phase just wrapped up with a second anticipated in the fall as part of the NEPA process, so this summer is an ideal time to visit the site. Getting to the project area involves a 50-minute drive southeast of Oakridge on Forest Service Road 21.

If you have questions about using Avenza or the field trip files, please contact Sarah Altemus-Pope at director@swfcollaborative.org

Learn About the Rigdon Landscape Project Through Our Guest Blog Series

Through multiple guest blog series, our partners have helped us tell the story of the Rigdon Landscape Project!

We formed the Rigdon Collaboration Committee in 2016 to work with the Forest Service on the Rigdon Landscape Project. We facilitated learning sessions, field trips, and roundtable discussions. After education sessions concluded, the group transitioned to roundtable discussions. This allowed committee members provided feedback to the Forest Service Interdisciplinary Team for future actions.

About the Landscape
The Rigdon landscape encompasses four Middle Fork Willamette sub-watersheds south of Oakridge, Oregon. Over the years, climate and fire have maintained mixed conifer forests and scattered wet and dry meadows. This landscape provides habitat for spring chinook, bull trout, and the northern spotted owl. Historical native tribes occupied this area and prescribed low intensity fires every 5-10 years. Over the last 150 years fire suppression has created dense forests. As a result the landscape has become less resilient and prone to high intensity wildfires.

Envisioning a Healthy Rigdon Landscape

A healthy Rigdon Landscape has a variety of habitats that is suited for all species of plants and animals and resilient to catastrophic fires.  This healthy landscape would have the variety and diversity that can be enjoyed by all.

Visiting the Rigdon Landscape

I started recreating on the Rigdon landscape in 1988 when I was 13 years old camping and deer hunting, this was the year I shot my first buck.  You can see Diamond Peak in the Background.

I have continued to recreate for the past 32 years in the area almost every fall.  In 2006 I landed a job with Seneca Jones Timber Company based out of Eugene Oregon.  Seneca owns 21,400 Acres within the Upper Middle Fork Willamette Watershed and many of these acres are located within the Rigdon Landscape.  I am the GIS/Inventory Forester and have the pleasure of spending much of my work time in this area.

Changes Throughout the Years

The landscape has definitely changed since 1988, with the change in the forest practices by the USFS, Catastrophic fires and lack of fire presence in certain areas. These changes have led to some less than ideal habitat conditions for a variety of species.



 

Favorite Memory

I have many great memories of this area, but one of my favorites is taking my children huckleberry picking in the fall for the first time and watching them enjoy the fruits of nature!

Favorite Areas

Bear Ridge has always been one of my favorite areas in the Rigdon Landscape, it has a variety of different habitats as it extends down from Diamond Peak.

 

Restoration Opportunities

SNC00375.jpg

I am most excited about the fuels reduction program on the landscape and reducing the risk of catastrophic wildfire.  I was on the Tumblebug Fire in 2009 and watched how it devastated thousands of acres in minutes.

Final Thoughts

I work and recreate in the Rigdon Landscape and have viewpoints from a variety of positions.  Growing trees for today and the future is our goal and is an investment we wish to protect.  This also creates a distributions of habitats on our lands within the landscape while providing jobs and economic benefits for the local communities.  As a recreationalist in this area I look forward to the habitat and landscape projects that will help diversify and help this landscape flourish.

Southern Willamette Forest Collaborative Participation:  I have participated in the Southern Willamette Forest Collaborative for many years in various capacities. The collaborative provides a constructive platform for diverse groups, agencies, and members of the public to share ideas and prospective in a respectful and productive atmosphere.

Envisioning a Healthy Rigdon Landscape

A healthy Rigdon landscape supports the type of habitat that should be there under natural ecological processes. These natural processes have been altered by conflicting land management activities and the interruption of natural processes. In the long term healthy, naturally functioning ecosystems will be less expensive to maintain and more resilient to anticipated climate change.

The Rigdon landscape encompasses four Middle Fork Willamette sub-watersheds south of Oakridge, Oregon. Click the map to the right to enlarge.

Visiting the Rigdon Landscape

I have both worked and recreated within the Rigdon Landscape for over 17 years. My professional involvement with the Rigdon project began in 2006 long before it was called Rigdon.

Changes Throughout the Years

Many of the large pine and oak trees we are trying to conserve have died since I began working on this project before it was called Rigdon. Semi‑open pine and oak stands have also been invaded by regenerating Douglas‑fir trees, exerting additional stress on the remaining pine and oaks. The shrub and forb understories are converting to barren areas of needle cast. Wildlife associated with pine and oak habitat are also diminishing. The remaining pine and oak habitats in the Rigdon project area will be lost if this project is not implemented.

IMG_5126.jpg

Favorite Memory

My favorite memory in the Rigdon area was seeing the positive response of pine and oak associated plant and wildlife species to the restoration conducted at Jim’s Creek. This gives me hope that we can accomplish similar responses on a landscape scale.

Favorite Areas

My favorite area in Rigdon is the Jim’s Creek Project demonstration area. The Jim’s Creek area is approximately 400 acres where the Forest Service restored pine and oak habitat by manipulating vegetation and restoring fire to the landscape. Native shrub, forb, and grass planting occurred, but many of these species responded naturally from the dormant seed bed. Jim’s Creek showed me what habitat was on this landscape for hundreds or more years. Restoring this habitat is possible and will produce a landscape more resilient to expected climate shifts in the future.

IMG_5382.JPG

Restoration Opportunities

IMG_5597.JPG

From a wildlife and wildlife habitat perspective, I am most interested in the pine, oak, and prairie restoration components of the project. Loss of these habitat types has occurred on a large scale in the southern Willamette Valley. The proposed road closures and decommissioning will also added needed security for wildlife from disturbance, as well as, assist restoration of some interrupted hydrologic processes. Finally, the proposed floodplain restoration will provide quality riparian habitat for numerous riparian associated and dependent species. Most riparian areas located on our national forests currently lack the structural and vegetative components necessary to support wildlife associated and dependent species that rely on this habitat type.

Rigdon Monarchs & Meadows: Milkweed in Rigdon


Guest Blogger: Kris Elsbree


Milkweed in Rigdon

The Rigdon Area in the Southern end of the Willamette National Forest is a dry mixed conifer forest that holds the northern extent of several species giving an oasis nestled in the Upper Willamette Watershed. 

Some of the unusual botanical characteristics include the abundance of Oregon White Oak and East side variety of Ponderosa Pine.  Taking a closer look at the plant communities in the meadows of this region and a distinct area can be defined as a habitat more likely to be found Southern Oregon.

One of the most picturesque and defining species to this habitat is Asclepias Cordifiolia; heart-leaf milkweed.  Coming to full bloom in late June and July heart-leaf milkweed becomes the center point of several meadows in the area being the largest plants with stunning flowers and seed pods.

Only a few years ago as the Rigdon Landscape analysis was underway there was only three known populations of milkweed in the Rigdon Area.  Tanya Harvey; a member of the Oregon Native Pant Society and the North American Butterfly Association and co-author of the Oregon Flora Volume 2; began looking at more potential sites for milkweed. 

Not only was Tanya able to find more milkweed but also discovered the first monarch butterfly in the area.  Since then Walama Restoration Project in Partnership with the U.S. Forest Service has been aiding those efforts by conducting milkweed and monarch butterfly surveys.

To date 16 meadows have been documented with milkweed and monarch butterflies.  The Western migration of Monarch butterflies is not completely understood, and the population has decreased over 90%.  This new known habitat may be a prime steppingstone for their migration and this new data will help the Forest Service better plan and implement projects to expand habitat for monarch butterflies and other pollinators and wildlife that share this habitat.

“We decided to access the area via an old road off of Road 2135, just past Big Pine Opening. A short bushwhack off the old road took us up to the south and lower end of the meadow complex (although we found an easier route back through more open woods on the way back). It only took a few minutes for us to spot the first monarch and the first caterpillar. Almost a week from when Sabine and I saw eggs at Monarch Meadow, it was about the right time for the eggs to start hatching.

We set about counting eggs, caterpillars, and adults in each opening. Crystal kept a count and recorded information about habitat while I took photos and put together a preliminary plant list. At this point in the year and less than 3000′ of elevation, most things were dried out, and even the milkweed was mostly beginning to go to seed, so I’m sure there will be many more plants to add to the list that we didn’t spot that day. What we did see looked pretty much the same as what was growing in Monarch Meadow, with the exception of a population of field pussytoes (Antennaria howellii), a species I’ve seen much higher up near Balm Mountain (see Another Exciting Day in the Calapooyas: The Sequel) and in one higher elevation spot in Douglas County.”

“I headed up the steep slope and through the woods to locate the waypoint Crystal had given me. I was not very hopeful as I really couldn’t imagine that there were any appropriate openings. But then I found the little sunny spot with some outcrop at the base, and there was the milkweed! It was only about a half-acre, but it had several fully blooming mock orange (Philadelphus lewisii) shrubs at the base of the rocks, attracting many butterflies and other insects.

While there weren’t very many large milkweed plants, a thorough survey totaled 37 plants, including 7 seedlings. Hard to imagine but it appeared that this population was expanding. I knew this species like shadier edges of rocky meadows, but I never imagined it could survive in such a small sunny spot. What really surprised me was that I found 2 monarch eggs and one (sadly) dead caterpillar on the ground beneath a milkweed plant. How did they find such a small population in such a small opening?! I’m calling this little spot Crystal’s Glade, and I definitely plan to revisit it in the future to see how the population is doing.”

Southern Willamette Forest Collaborative Participation:  I have been an active member since 2016. I am currently an ex-officio, non-voting board member and I regularly participate on the Implementation Advisory Committee and the Rigdon Collaboration Committee.

 

Envisioning a Healthy Rigdon Landscape

Rivers and forests where ecosystem processes are preserved with land management, recreation, and other uses. Clean water and abundant fish and wildlife populations.  Patch complexity across the landscape where there’s a diversity of habitat types – wild rivers, meadows full of wildflowers and pollinators, fire, healthy forests, and beautiful views.

I began working for the Middle Fork Willamette Watershed Council in 2015 and the first restoration project we developed was the Staley Creek Floodplain Restoration Project in partnership with the US Forest Service Aquatics Team.  We implemented that project in 2017 and began developing the Coal Creek Floodplain Restoration Project, which was implemented in 2019.  We’re still working on building the Middle Fork Trail re-route as part of that project and expect it to be completed summer 2020.

Sugar Pine Cone

Before coming to the Middle Fork, I had never recreated in the Rigdon Landscape, but to do my job well, it’s imperative that I know the watershed intimately.  That need led to a crash course in recreating in the Rigdon area, which has been incredible.  I’d spent the last 10 or so years working in agricultural landscapes in the mid-Willamette Valley and on the Oregon coast and was instantly drawn to Rigdon because of its feeling of rugged wildness (and limited crowding), as well as forests more reminiscent of where I grew up in southern Oregon.  There are even sugar pines which are home to me.

Changes Throughout the Years

The changes I notice are the active restoration actions that my organization and our partners are responsible for – the two floodplain restoration projects, a trail re-route of the Middle Fork Trail, the burning at Jim’s Creek. Other noticeable changes that aren’t human-caused are new river meanders and the activation of new and different side channels.

Favorite Memory

I can share a least favorite memory!  Early in my explorations of Rigdon, I made the mistake of trying to hike the trail from Jim’s Creek to Moon Point in early summer.  About ¾ of the way up, my poor dog and I were completely engulfed by voracious mosquitos.  I looked like the character Pig Pen from Charlie Brown – but instead of dirt, it was a swarm of mosquitos.  My poor dog had a look of remorse on her face. Long sleeves and pants did nothing to mitigate their attack.  Instead of hiking as intended, I was running the trail – in hiking boots, with my daypack.  It was the most miserable time!  We recovered on the Middle Fork Trail where the mosquitos were almost absent. 

 

Favorite Areas

I also enjoy regular, unstructured explorations of the Staley Creek floodplain project – to look at the active changes that are occurring there.  Rainstorms offer moments of anticipation and a learning opportunity to understand how the river interacts with and sculpts its floodplain.  Grasses, sedges, rushes, and other woody plants are emerging; cobbles, rocks, sands, and logs are sorting; and big, deep pools are forming.  Water moves in almost every direction, at varying depths.  I don’t often seen critters when I’m out, but know they’ve been there from the beaver chewed sticks to the tiny prints of what I’m betting is a river otter.

Restoration Opportunities

I am most excited about a landscape scale restoration vision and approach that pairs upland and floodplain restoration – opening up meadows and dry-mixed conifer forests and using some of that wood to restore nearby rivers and floodplains.  Learning how to manage the landscape with fire – both controlled burns and natural ignitions – will be essential.  If we can work to reduce fuel loads in the uplands, fire can become our friend, not our foe. 

We know this landscape has seen human use and interactions long before white settlers arrived.  I envision restoration actions that incorporate and engage the community – where the community has a sense of ownership over the work – and a connection to the place.  Community volunteers have worked with us to rescue fish at our floodplain restoration project.  Volunteer trail crews cleared and built new sections of the Middle Fork Trail.  High school students have helped us imagine interpretive signage.  Connecting our community to the land and water is one the most satisfying aspects of my work.

Envisioning a Healthy Rigdon Landscape

The Rigdon landscape encompasses four Middle Fork Willamette sub-watersheds south of Oakridge, Oregon. Click the map to enlarge.

A healthy Rigdon landscape would include: natural meadows, a mature varied-species forest, clean air and water, a safe balance among all trail users, a well-maintained Middle Fork Willamette (MFW) trail, adequate designated parking for horse trailers at trail entry points, and more regulated, designated opportunities for camping, including camping for horses.

A major opportunity we are happy to contribute to, is increased bull trout populations and  family fishing potential. Our Back Country Horsemen (BCHO) commitment to this area goes beyond just equine trail use. We have donated money and time on bridges over sensitive wetlands and bogs along the trail, helping to mitigate sediment flows.  

 

Visiting the Rigdon Landscape

We have worked and recreated on the Middle Fork Willamette (MFW) trail for 25 years. We’ve ridden horses and maintained trails throughout the years, to include being responsible for Keele Crossing cedar puncheon (built in 2005.) Through Back Country Horsemen (BCHO), we have helped maintain the MFW Trail for 20 years and contributed funding for rebuild of several bridges on MFW trail.

Changes Throughout the Years

We’ve seen changes due to significant mountain bicycle pressure on the MFW trail. Some of our group have experienced dangerous bicycle encounters. We avoid taking horses on the MFW trail on several high use weekends in the summer when bicycle rallies and concessionnaire trips occur. As a rule, we avoid taking horses in the entire MFW area during summer weekends. 

 

Favorite Memories

0933367-R1-019-8.jpeg

Taking green horses along the Middle Fork Willamette Trail 20 some years ago and naming the “Weeping Wall”, which abuts the trail along the lower section. Also, the discovery of many lady slippers (Calypso) wildflowers hidden along the trail brings delight in spring. We love the lighting that enhances the trees as light filters through heavy moss in summer and as the trees change colors in the fall.

Another favorite memory is the group celebration of the members of our BCHO chapter upon completion of “Keeles’ Crossing.” We split the cedar planks on site, dug out the mud, laid cedar stringers and the hand-hewn planks for the 15 foot bog crossing. To cap it off, we took a group photo of the crew and favorite dog on the completed crossing. Smiles of satisfaction with a job well done.

Other Favorites

Areas: the Middle Fork Willamette Trail and the Youngs Rock Trail for purposes of horseback riding, and hiking, and the river for photography, and potentially for fishing.
Meadow: Rigdon Meadows. 
Tree Species: Ancient big leaf maples, large Pacific Yews and the old growth cedars and Ponderosa Pine.  It would be wonderful if some aspen could be introduced to the higher meadows.  
Creek or River: Indigo Creek and the pristine Middle Fork Willamette reach above the dam. The Staley Creek rehab is to be commended.

 

Final Thoughts

We would like to mention, we are appreciative of the entire staff and membership of the Southern Willamette Forest Collaborative for their efforts on behalf of Middle Fork restoration.

Envisioning a Healthy Rigdon Landscape

The Rigdon landscape encompasses four Middle Fork Willamette sub-watersheds south of Oakridge, Oregon. Click the map to enlarge.

I personally love seeing forests in the Rigdon area with a mix of species like incense cedar, chinquapin, madrone, Ponderosa pine, yew, and Douglas-fir - areas that were often more open in the past, and had pretty frequent fires.

There’s no doubt that human management (fire suppression, logging) has changed these forests over the past century. To me, it is important to recognize our role in creating these changes and consider the importance of these mixed conifer forests and in the future landscape and the fire that help them thrive, but it’s also important to consider the importance of the habitat and forests that have developed over time. The denser 100-year old forests that have grown in many places (or that were always more dense and moist) are also really important for native species like red tree voles and northern spotted owls - especially when you consider the heavily logged and fragmented landscape these older forest pockets are scattered among.

Balancing the needs of these species and importance of this type of habitat with the more historic, more open mixed conifer forests and the ecosystem components that come with those is difficult.  And while restoration activities can play a role in finding that balance, we also need to consider how we can let some of the forests develop on their own without more “management”, or how to allow natural processes like fire to play the role they are meant to.  A healthy landscape has all the ecosystem pieces it needs for adapting to change, and can function as more of a connected ecosystem that supports native species of all kinds and can adapt to climate change and natural disturbances better. I’m excited to see more floodplain restoration within the landscape and using fire (prescribed and allowing more naturally-caused fire) as a tool for restoration.

I’ve visited the upper Middle Fork for a long time - hiking and camping, etc. - though often higher up in the watershed than the mixed conifer area of Rigdon. In my work with Oregon Wild, I’ve toured Forest Service projects (including the Tumblebug Fire area right after it burned) and led hikes and trips. I’ve also been on the Middle Fork Willamette Watershed Council for several years so have supported and toured projects like Staley Creek and Coal Creek.   

 

Favorite Memory

Staley Creek Floodplain Restoration Project

Staley Creek Floodplain Restoration Project

Putting on waders and climbing around in Staley Creek a year after the floodplain project was completed was wonderful. I haven’t done much walking around in rivers, and doing so gives you a really unique perspective on how the water flows, where there is good habitat for fish, and how the forest and vegetation influences the stream (and vice versa). I love opportunities to see how ecosystems work, and how restoring ecosystem processes (from active floodplains to more natural fire regimes) benefits so much more than one species. 

 

Final Thoughts

I’m super excited that wolves are moving into the Ridgon landscape area and upper Middle Fork watershed. To me, this shows that areas where natural processes like fire are occurring (and connected across landscapes) can help the whole ecosystem (including wildlife) recover from decades of human-caused problems.

Rigdon Fire History: Fire in Old-Growth Douglas-fir Stands


Guest Blogger: James Johnston

Any time you can be in the woods hiking around and calling it work it’s fun, but reconstructing historical fire in old-growth Douglas-fir forests is…. less fun than in other areas.  For starters, the slopes tend to be really steep and the trees are really big and hauling around gas and giant wood samples gets old. 

Finding fire scarred trees in stands with oak and ponderosa pine is relatively easy.  Ponderosa pine typically has a cat face like this one which allows you to easily see evidence of historical fire.  You saw out a partial cross section and use the unique pattern of wide and narrow rings to cross date that sample, and assign to each of those fire scars a calendar year. 


 

In old-growth Douglas-fir/western hemlock forests you can rarely see visual evidence of historical fire and so I’ve been using a chainsaw to basically excavate these large stumps left over from logging operations.

If you crack open enough of these stumps, you can find fire scars buried in these giant chunks of wood.  They look like this:  


 

Most scientists assume that these old-growth Douglas-fir/western hemlock forests go hundreds of years without fire, and when they do burn, it’s generally stand replacing fire. But when we crack open these big stumps, we are seeing far more evidence of historical fire than predicted by theory.

Rigdon Fire History: Fire in Oak Stands

Guest Blogger: James Johnston


Hunting for fire scars is a ton of fun.  My favorite spots within the Youngs Rock-Rigdon planning area are those areas with oaks. 

Oregon white oak (Quercus garryanna) is an amazing tree.  It is relatively slow growing and usually can’t compete with Douglas-fir.  It is extremely fire resistant because it has thick, protective bark and adventitious buds—buds that can quickly resprout following fire damage.  Oak savannahs and woodlands are archetypal fire-dependent ecosystems.  Historically, they burned very frequently which promoted dominance by oaks and excluded conifers that were not quite as well adapted to very frequent fire. 

oaks.png
understory.png

Many oak stands up the Middle Fork are kind of sad because younger Douglas-fir has over-topped the oak and killed it.  Douglas-fir competes with the oak for water and light.  White oak needs an enormous amount of light—usually light from all directions—in order to survive and grow new leaves every year.   These oaks (right) died just within the last year or two.  

Right next to these dead oaks was a ponderosa pine stump (at 43 29.576, -122 23.091) that was an incredible source of data.  It had rings from when it was cut down in 1956 to the year 1344 (in that same year, at the Siege of Algeciras in Spain, a European army used gunpowder for the first time).  And it recorded fires in 1849, 1842, 1839, 1833, 1829, 1826, 1822, 1818, 1815, 1805, 1792, 1790, 1788, 1783, 1781, 1779, 1775, 1768, 1763, 1754, 1744, 1739, and 1728.  As far as I know, this site experienced more frequent historical fire than any site where fire has been reconstructed in the Pacific Northwest.

Rigdon Fire History: Fire History Research

rings.jpeg


Dendroecology is the application of tree-ring analysis to ecological questions.  North American conifers tend to live for a long time and they lay down annual growth rings that can be used to learn all sorts of interesting things about the past. 


One of the oldest and most interesting uses of dendroecology is fire history reconstruction.  We often only have several decades of reliable direct observation of fire in many landscapes.  Tree-ring based fire reconstructions allow us to gain knowledge about fire occurrence over hundreds of years.  Disturbance processes have often been significantly altered by management practices over the last 100 years, and so tree-ring fire histories allow us to determine what the natural range of variability—or natural fire regime—is like for different forests. 

Our tree ring lab at OSU is currently working to reconstruct fires along the upper Middle Fork Willamette River in the vicinity of the Forest Service’s Youngs Rock-Rigdon project area.  Information about the natural range of variability in fire disturbance should be useful in designing silviculture treatments that will restore historical structure and composition. 

Tree ring-based fire history reconstructions are painstaking and time consuming.  The first part of the process is the most fun—searching an area of interest for fire-scarred trees.  When we find a stump or old log that shows evidence of past fire, we saw out a few cross sections with a chainsaw. 

samples.png

We’re looking for wood that has scars where a past fire killed the cambium—the living tissue of the tree—and the tree survived to lay down wood over the scar.  The arrow in the photo points to a fire scar.  We sand these samples to a fine polish so they look like this:

crossdate.png

Trees are hydro-climatically sensitive, meaning that their annual growth varies as a function of climate.  Trees lay down narrow rings in years that are warm and dry and wide rings in years that are cool and wet.  The pattern of wide and narrow rings during different time periods is as distinctive and unique as human fingerprints.  These unique patterns allow us to cross date—or assign to each ring a calendar year.  Calculating the average length between the years where fires scarred the tree provides information about fire frequency in a given area. 

All of the wood we collect in the field eventually finds its way to our tree ring lab at Oregon State University.  Here’s the lab:

lab.png
machine.png

We have a really cool machine in the lab that we use to measure each individual tree ring to the nearest hundredth of a millimeter.  We use a variety of algorithms to match the tree ring measurements to a master chronology of tree ring widths to determine in which year each ring was laid down.  The big machine:
